Hewlett Packard HP70908A 22GHz RF section ROM checksum error

[Lightbox Solar]

Hi,
My HP70908A RF section has developed error 7009: ROM #2 checksum error. Just wondering if anyone has an image / is willing to make one?
The chip is A12U7, a Xicor X2864AD 8k x 8 EEPROM. HP programmed part no is 70908-80001

The unit still boots and seems to run fine

If the ROM images aren't already available on ko4bb.com, I'd recommend posting your inquiry to the HP-Agilent-Keysight-equipment group on groups.io.  There are quite a few HP 70000 owners who hang out there.

Hey KE5FX, it's been a while - I think you helped me out 10+ years ago on the Yahoo Groups HP repair page to fix an issue with the 70908A's discriminator loop when I first got it!
Had no idea those guys moved to another platform - will check it out.

Cheers!
